IPC: C25D1/00
Filed: 1954-11-23
Abstract: 789,227. Electrodeposition. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Jan. 9, 1956 [Nov. 23, 1954], No. 33882/54. Class 41. In a method of electroforming wherein a material, e.g. copper, is deposited electrolytically on to a form 14, 18 having a re-entrant angle, a conducting member 8 is positioned in relation to the angle to guide an increased flow of current thereto to facilitate deposition there. The method is applicable to making waveguides, and flanges 15, 17 thereon are fitted on the arms 14, 18 of the form, which may be stainless steel, each flange having a skirt 16. Current is led to the form 14, 18 by a lead 2 screwed at 3 through insulation 4 to the form, wax or lacquer 20 protecting the flanges 15, 17. An insulating collar 19 supports the member 8 with one end 9 adjacent the angle, the other end 8A lying parallel to the anode in the bath. When the deposited layer is 0.030 inch thick, deposition is stopped, and a blob of solder 13 put in the angle, or a file may be drawn thereacross to close the gap. Deposition then continues for 1 hour at 10 amps. per square inch and thereafter at 60 amps. per square inch. The bath may be 200 gms. per litre copper sulphate and 55 gms. per litre concentrated sulphuric acid. The form is removed by warming and dismantling. Alternative forms which may be dissolved out are polythene flashed with silver, aluminium and wax, the solvents of the last two being caustic soda and trichlor-ethylene, or a low-melting point material may be used. When non-heat-resistant forms are used, a copperbronze paste in gum lacquer may be substituted for the solder 13. The form and member may be rotated during deposition, e.g. at 50 r.p.m. Specifications 691,128, [Group XL (b)], and 788,545 are referred to.

Abstract: 340,094. Powder boxes. ROSENTHAL, B., 27, NÚpszinhßz Utca, Budapest. Nov. 9, 1929, No. 34298. Convention date, Aug. 7. [Class 18.] A powder box comprising a container with a perforated lid is enclosed by a casing which, in opening, moves in a rectilineal direction and rotates a vanewheel in the container to deliver powder through the holes in the lid. In an example, a box b enclosing a powder container a is surrounded by a casing c in two parts which can be pushed together to enclose the box completely. A perforated tray i closing the container a is held therein by two resilient tongs l and is closed by a hinged mirror which springs up when the casing is opened. One of two studs e limiting the outward movement of the casing parts c has a rack o pivoted thereon, the rack engaging a spur-wheel g keyed on to a pin which extends into the container a and carries a blade or vane-wheel. A spring p keeps the rack and spur-wheel in engagement. When the halves of the casing are pulled apart, the mirror springs up and the vane-wheel is caused to rotate and deliver powder through the holes in the tray where it is received on a puff. A ratchet wheel and rack may be used so that the vane-wheel rotates only when the casing is, for example, being opened. In another construction, the box and casing are of the drawer-and-shell type, the box being pulled out by a knob or tab, and a depression to hold a lipstick &c. may be provided in the lid of the powder container.

Abstract: 1,034,098. Comparators; selective signalling; road - traffic measurements. STANDARD TELEPHONES & CABLES Ltd. Aug. 30, 1963 [Sept. 15, 1962], No. 34450/63. Headings G4A, G4D, G4H and G4Q. The relationship between numbers registered in two counters is indicated by the application of potential to one of a number of outlets under the control of resistors switchable into circuit according to the states of the counters. Two counters of binary type (Fig. 4, not shown) include a relay in each stage to control contacts a1-a7, b1-b7, respectively, arranged in parallel with associated resistors R1a-R7a, R1b, R7b. Operation of each stage opens the associated contact to put the associated resistor into circuit. Assuming that counter A reaches full capacity first then contact aI closes and transistor T1 conducts to produce a comparison of the state of counter B with that of A. Zener diodes Z1, Z2 apply stabilized voltages to the resistor chain R1b-R7b, the total resistance of which depends on which contacts are open. This chain therefore applies an appropriate potential to transistor T2 to produce appropriately weighted potentials on terminals e-l. These potentials are applied to a thresholdvalue indicating circuit, Fig. 3, comprising a succession of transistors Tr of which five are shown. As the contacts a1-a7. Fig. 2, open and the count in B increases so potential is removed progressively from terminals 1/p-1/t, so indicating step-by-step the relationship between the two counts. The apparatus may be used in road traffic signalling systems.

After the section 3 has been severed, the body 1 is moved in the direction of the arrow and the strip 2 is moved so that the section 4 is located thereover. In an alternative embodiment the strip 1 is annular and the sections are located radially thereon.

A rotary pump shaft 11 is sealed by means comprising first and second mechanical seals 14 and 15 axially separated by an enclosed chamber 30c and each by-passed by a pressure reducing cell 63b and 63c respectively providing an open fluid conduit. In the embodiment shown for a high pressure pump the shaft is sealed by four mechanical seals 12, 13, 14 and 15 arranged in series. The seal 12 comprises a rotary sealing ring 35 sealed to the shaft by a cup packing 34 and having a face 36 urged by springs 32 in a sleeve member 26 into facial sealing contact with face 37 of a stationary sealing ring 38 housed in a back-up member 23.

Resistors 50 to be fed to bowl 10 and thence to be discharged along spiral track 14 by vibrator 106 are fed as a tangled mass on to spokes 36 of disc 80, disc 80 being secured to disc 82 which lies on head 54 secured by member 32 to the base 48 of the bowl 10 so that the spokes 36 vibrate to permit the individual resistors 50 to fall between the spokes 36 and to be discharged at 70 into the-bowl 10. When the feed of resistors 50 from the spokes 36 to the bowl 10 is to be diminished, as sensed by.sensing element 40 positioned within bowl 10, cylinder 60 is operated to cause the elevation of rod 90 to engage stud 88 secured to disc 80, whereby the spokes 36 are raised to free them from vibration.
